EQ6720LTFCEV丨Dongfeng Hydrogen Fuel Cell Coach
EQ6720LTFCEV is a hydrogen fuel cell bus developed by Dongfeng Special Automobile Co., Ltd. It is 6.72 meters long and is positioned in medium-sized cities or urban-rural connection scenarios. Its core power system uses a hydrogen-air proton exchange membrane fuel cell, coupled with a permanent magnet synchronous motor to achieve zero-emission operation. The vehicle has a curb weight of approximately 5950-6100kg (the upper limit increases when air conditioning is optional), a rated passenger capacity of 24-28 people, a maximum speed of 69km/h, and a wheelbase of 3650mm, taking into account flexibility and passenger efficiency. The vehicle is equipped with an ABS braking system and a satellite positioning recorder as standard, and can be equipped with air conditioning, ventilation skylight, and a customized side window structure to meet diverse operational needs.
As part of EMAC, DuraMac provides a complete powertrain that integrates with DCEC engine, Fast-Eaton clutch, FAST-CAT transmission, Dongfeng-DANA axle, and Komman air suspension. At the same time, the electrification of automobiles is a certain future; DuraMac also gets involved with the EV powertrain systems.
We provide full life cycle services for all customers, from design to power system supply, from installation to commissioning, from after-sales service training to spare parts supply, from troubleshooting to overhaul technical support.
Advantages of EQ6720LTFCEV
The fuel cell system has a complete and reliable structure, using permanent magnet synchronous motors and integrated controllers, which are safer and more efficient.
The vehicle instrument can display the relevant data information, alarm information, and communication status of the electronic control system, battery system, motor system, electrical accessory system, and fuel cell in real time, and can promptly alarm the driver when there is insufficient residual hydrogen pressure or fuel cell system failure.
Using GPS and GPRS network technology, remote monitoring, data collection, data analysis, safety warning, fault diagnosis, etc., of new energy vehicles can be realized to improve the safety of vehicle operation.
